| Abstract |
The Active NPC VSC (3L-ANPC-VSC) features a higher degree of controllability than standard NPCconverters, allowing a better temperature distribution among the semiconductors. With the aid of aPredictive Control strategy, a new temperature balancing method for the 3L-ANPC-VSC is introduced.The algorithm is implemented in Matlab and compared with the 3L-NPC-VSC using experimental dataof 4.5 kV Press-pack IGBT and Diode for the calculation of the losses. The comparison shows a potentialfor increasing the output power of the 3L-ANPC-VSC topology. |
